If you've forgotten your Windows 10 password, there are several ways to retrieve or reset it:

If your PC is on a domain, your system administrator must reset your password, then you can try UUkeys windows password mate, or ophcrack ,or Ntpassword.

If you're using a Microsoft account, you can reset your password online. If you’ve forgotten your Microsoft live account password, you can reset it online via the live.com or outlook.com website. This method requires you to know either the alternate email address or phone number you previously added to the account.

If you're using a local account, use your password hint as a reminder.

If you still can't sign in and are using Windows 10, you must reinstall Windows.
